Hi! I have PD50. I tried to connect all my toys to it (DVD player, VCR, digital TV set top box, DIVX player). I hoped that the number of AV inputs is OK, but ... AV1 seems to have a problem! There are just two inputs which support RGB: AV1 and AV4. But if I connect something to AV1 using RGB, the quality is bad ... you can see stripes there (especially when the picture is dark). AV4 does not have this problem. AV1 in non-RGB mode works good as well. Do you know how to solve it? Is just my TV wrong or is it a common "feature"?
